Conglomerates and sandstones of the Eocene Carmelo Formation were deposited by sediment gravity flows, in relatively deep water, in a submarine canyon probably comparable to the present-day Monterey Canyon.

The Commonwealth of Virginia's Department of Geology and Mineral Resources has their offices in Charlottesville, Virginia. Outside their building is an exceptional collection of large rock samples from across the state. Samples include igneous, sedimentary, and metamorphic rocks from all five physiographic provinces, a...

These are the rocks that hosted much of the gold on the west slope of the Sierra Nevada Mountain Range for California's 1849 Gold Rush. This roadcut on Interstate 80 offers no pullouts for convenient GigaPanning - I had to park at a CHP station about half a mile east of here and walk back on the shoulder to get this s...

The Tertiary Ogallala Formation is best known as the host rock for one of the largest freshwater aquifers on Earth. In Ellis County, Kansas the Ogallala is exposed at the surface and forms resistant hill-capping exposures such as the ones seen in this Gigapan.
My largest Gigapan yet at 2.45 gigapixels, this monster...

Castle Rock is an erosional remnant of Upper Cretaceous Niobrara Formation (Smoky Hill member) chalk, located in southeastern Gove County, Kansas. The chalk badlands at this locality owe their preservation to a caprock of Ogallala Formation conglomerates, visible atop the cliff at left and in boulders on the slope.

Palisade Falls in Hyalite Canyon are a remarkably picturesque site. The falls drop over a columnar jointed basalt flow which was erupted atop Eocene (?) conglomerates (Absaroka volcanics?).
This GigaPan is about a tenth of the size of the one I intended to shoot. Unfortunately I hadn't carried a spare set of batteri...
